Abstract (en)
[origin: US2004242746A1] A composition comprising a thermoplastic and a CO2 releasing material; wherein the CO2 releasing material comprises: a) a carbon and oxygen containing salt of an alkali or alkaline earth metal; and b) an acid; the CO2 releasing material has a sufficient amount and ratio of the carbon and oxygen containing salt of the alkali or alkaline earth metal and the acid so that, in the presence of water, the CO2 releasing material reacts to release CO2 gas through the thermoplastic into a surrounding environment.
